As we are all painfully aware, IT security comes in many forms, from technical details to physical barriers. But a word of advice: Double-check all your new security measures. Then step back and think through anything that could be related to the changes you put in place. Finally, check to make sure those, too, are secured adequately.
I worked at one company some years ago where I was given an office near a server room. Not long before then, the IT execs had asked for measures to be taken to better secure the servers.
